FAQ

Is it safe to buy refrigerants online from CoolmateGas?

Absolutely. Our refrigerants come from verified and certified manufacturers, each cylinder is properly labeled, leak-tested, and shipped via UPS ground service. You can order refrigerants online with confidence.

What's the replacement for this Gas?

Currently, there are no fully compatible alternatives, but alternative solutions depend on the equipment type:

• R407C

Commonly used for retrofitting

Similar operating pressure

Requires system adjustments

• R438A (MO99)

Compatible with mineral oil and POE oil

A popular R22 replacement, some users choose it instead of R421A

Not a perfect match for R421A, but can be used in many R22-based systems

• R22 (Original refrigerant)

Systems that originally used R22 but have been converted to R421A can theoretically revert to using R22, provided that the supply and price of R22 are acceptable in your region.

• R32 / R454B

Not a direct replacement

Requires a completely new air conditioning unit

Much lower Global Warming Potential (GWP) and higher efficiency

Common in modern HVAC systems

⚠️ Important Note: Replacement options depend on the system configuration. Compatibility should be assessed by a certified HVAC technician.
